Title: Potential measuring device
Inventor: TODOKORO HIDEO
IPC: H01J37/28
Filed: 1984-01-11
Abstract: PURPOSE:To obtain a potential measuring device, which makes it possible to observe a wide visual field by making the deflection fulcrum of an electron beam in the position of a grid. CONSTITUTION:An electron beam 1 is deflected by the scanning coils 2 and 3 so as to go through the center 4 of a magnetic field lens 6. Next, the electron beam is inversely deflected through the third scanning coil 14. Thereby the point, at which the deflected electron beam cuts the axis, (the deflection fulcrum) is arranged to match the second grid 8 forming a potential barrier. Thereby, the opening of the second grid 8 can be made extremely small thus enabling a wide visual field to be observed without lowering a potential measuring performance.

Title: Radiographic information recording and reading device
Inventor: HORIKAWA KAZUO
IPC: H04N1/00
Filed: 1988-01-08
Abstract: PURPOSE:To make the entire of the titled device small in size by forming an accumulating phosphor layer on a recording belt and setting the intervals between two pairs of roller parts among recording belt carrying roller group which lays the recording belt to 1-1.5-time length of the screen of the maximum size. CONSTITUTION:The recording belt 1 which is an endless belt, on all the surface of which the accumulating phosphor layer is formed, is laid by a 1st roller part 40 consisting of two rollers 41 and 42 and a 2nd roller part 50 consisting of two rollers 51 and 52, which are arranged apart from the 1st roller part 40 by a specified distance L, and cyclically carried in a direction shown with an arrow. The recording belt carrying roller group is constituted only of the 1st and the 2nd roller parts 40 and 50. The distance L between two roller parts 40 and 50 is nearly as long as one image formed by image recording(photographing) and radiographic information is accumulated and recorded in the entire upper part of the recording belt by executing photographing once. Now, it makes no difference that the distance L between two roller parts is slightly larger than the device if it is <=1.5, supposing that the size of the image of the maximum size in which photographing is executed is 1. Thus, the scale-down of the entire device can be enhanced.

Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To make appropriately and efficiently performable superimposition and demodulation of an electronic watermark information by appropriately detecting a synchronizing signal at the time of embedding the electronic watermark information. SOLUTION: The peak of an input signal is detected by a trigger detecting part 11, and the section made to be a unit of the embedding process of the electronic watermark information is decided.

In an encode part 14, a carrier wave signal of the specified frequency is produced in a carrier wave producing part 15 and subjected to PSK(phase shift keying) modulation in a PSK modulation part 16 by the electronic watermark information and spectrum-spread in a PN spreading part 18 by random number data of PN group produced in a PN producing part 17, then the obtained modulation signal is amplitude-modulated in an amplitude modulating part 19 in accordance with the representative value obtained by the representative value calculating part 13. This modulation signal is superimposed to the input signal by an adding part 20 and recorded on the recording medium.

Title: Pressure gauge
Inventor: IKEDA KIYOUICHI
IPC: G01K11/26
Filed: 1979-01-11
Abstract: PURPOSE: To expand the range of object to be measured by determining the intended pressure from the characteristic frequency of the vibrator when it is vibrated with multiple oscillation modes.  
     CONSTITUTION: Spot faced holes 16, 18 or the like are provided at an interval of 90° on the thick cylindrical section 14 of the vibrator 1 comprising a stepped container having a step 11. Oscillation detecting piezoelectric elements 2 and 3 and driving piezoelectric elements 4 and 5 are mounted on the bottom of the vibrator facing each other and connected to an output circuit 180 through addition circuits 100 and 160 and subtraction circuits 110 and 170 and the like. As a result, output signals Va and Vb of charge amplifiers 60 and 70 are multiplied by a fixed value from coefficient circuits 80 and 90 to form signals Vc and Vd corresponding to only the quartic and secondary oscillation modes and the signals Ve and Vf corresponding thereto are outputted via low pass filters 120 and 130 and amplifiers 140 and 150. Thus the addition circuit 160 and the subtraction circuit 170 output the signal for vibrating the vibrator 1 with the secondary and quartic oscillation modes through the piezoelectric elements 4 and 5 while the output circuit 180 outputs the signal corresponding to the pressure being measured. Accordingly, the fluid pressure of any density can be measured without being restricted by the operation temperature.

Abstract: PROBLEM TO BE SOLVED: To produce the subject compound useful as an intermediate for a medicine of an agrochemical in high yield by reacting an m-substituted-α- bromoethylbenzene or an m-substituted-α-haloethylbenzene as a starting raw material under mild conditions. SOLUTION: Dehydrobromination of an m-substituted-α-bromoethylbenzene of formula I (X is a halogen or trifluoromethyl) is carried out in the presence of a base or dehydrohalogenation of an m-substitutedα-haloethylbenzene of formula II (Y is chlorine or bromine) is carried out in the presence of a base and a phase transfer catalyst. In these reactions, preferably, the dehydrohalogenation is carried out under heating and reduced pressure, and an m substituted styrene of formula III is isolated by distillation. A hydrogensulfate compound such as tetrabutylammonium hydrogensulfate is preferable as the phase transfer catalyst. A reaction from a compound of formula I to a compound of' formula III proceeds at a lower temperature than the case in which III-substituted-α-chloroethylbenzene is used as a starting material.  Dehydrohalogenation in the presence of a base and a phase transfer catalyst proceeds under further milder condition than dehydrohalogenation in the presence of a base.

Title: Data transmission device
Inventor: KONDO TOSHIYUKI
IPC: H04L29/08
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To easily manage which device each device performs synchronous communication with in the case of communication by using a parallel interface by holding a flag that shows the input-output of synchronous communication data and a node, etc., of a device that is an object of the input-output of the synchronous communication data. SOLUTION: For instance, a device A requests a device B 102 to transfer synchronous communication data. When the device B 102 receives a transfer request for the synchronous communication data from the terminal A 101, first, it acquires a channel and a band for synchronous communication from a device D 104 that is a bus manager. Later, it retrieves a register whose flag part shows an unconnected state. The flag part of the register that is selected as an empty register is changed from the state that shows an unconnectedness to a state that shows connectedness (e.g. '1') and stores the node ID of the device A 101 in an area, where the node ID of the register is stored. And it starts a transfer of the synchronous communication data with the device A101.

Title: Amplifier
Inventor: HIRABAYASHI ATSUSHI
IPC: H03F3/34
Filed: 1986-01-10
Abstract: PURPOSE:To keep the DC potential constant even at temperature rise by supplying an offset current of a dummy amplifier circuit to an output terminal of the amplifier circuit via an inverse amplifier circuit. CONSTITUTION:Since the dummy amplifier circuit 20 has the same characteristic as that of the amplifier circuit 10, an offset current ios is outputted from the dummy amplifier circuit 20, equal to that of the amplifier circuit 10. The offset current ios is fed to the inverse amplifier circuit 30, but the level of the inverting input of an operational amplifier 31 has nearly equal potential to that of the non-inverting input and then no current flows, the offset current ios flows to a resistor 32, resulting that the DC offset component ios.RL is canceled. Even when the DC offset of the amplifier circuit 10 and the dummy amplifier circuit 20 varies individually, the DC offset is made nearly equal and then canceled, thus no DC potential VO is varied.
